MathStar Announces Third Quarter 2007 Financial Results


HILLSBORO, Ore., Nov. 7, 2007 -- MathStar, Inc. (NASDAQ: MATH), a fabless
semiconductor company specializing in high-performance programmable logic, today
announced results for its third quarter of 2007, ended Sept. 30, 2007. Revenues
in the third quarter were $63,000, compared with $28,000 in the same period last
year. During the three months ending Sept. 30, 2007, the company completed and
invoiced the first phase of a multiple element arrangement for $78,000. The
amount was not recognized as revenue during the quarter as not all of the
criteria for revenue recognition were met. The company will recognize the full
value of the arrangement, totaling $156,000, upon completion of the remaining
elements, which is expected to occur in the fourth quarter.

Net loss per share was $0.10 in the third quarter of 2007, compared with a loss
of $0.39 per share in the same quarter a year ago.

"We are starting to see the revenue ramp on our Arrix(TM) FPOA products" said
Doug Pihl, president and chief executive officer. "We believe that 2008 will be
the year we prove to the programmable logic market that a new player has
arrived," he said.

For the quarter ended Sept. 30, 2007, research and development expenses
decreased $1.6 million or 38 percent to $2.7 million, from $4.3 million reported
in the same quarter a year ago. The decrease was a result of reductions in
engineering material of $1.3 million due to the tapeout of the Arrix chip last
year, combined with lower outside development costs and lower administrative
costs. The decrease was partially offset by the increase in employee related
expenses.

Selling, general and administrative expenses decreased $0.4 million or 16
percent to $2.2 million, compared with $2.5 million in the same quarter a year
ago. The decrease was a result of lower non-cash charges related to restricted
stock issued in earlier periods offset by increased employee recurring charges.

The company will present a full business update during a conference call today,
Wednesday, Nov. 7, at 1:30 p.m. PST. To listen to the call, please dial
